Starting this week, the overall weather situation on the mainland will undergo major changes, and the distribution of rain and heat will change with the change of the position of the subtropical high. Among them, the rainy areas in the south of the Yangtze River and the middle and lower reaches of the Yangtze River will become sunny and hot; The high temperature weather in North China, Huanghuai and other places will decrease, and the rain will gradually increase.
Heavy rainfall of the "Great Shift".
Simplified version
Middle and lower reaches of the Yangtze River: I want to rest......
North China, Huanghuai: I'm going down!
Detailed version
Since late June, the main rain belt of the mainland is located in the eastern part of the southwest region to the middle and lower reaches of the Yangtze River, with a cumulative rainfall of more than 400 mm in Zhejiang, Anhui, Jiangxi, Hubei, Hunan and other places, more than 1 times more than the same period in normal years, and more than 90 national stations have experienced extreme values in the same period in history.
It is expected that by tomorrow, the position of the main rain belt in the southern part of the mainland will still not change much, and heavy rainfall will continue in Guizhou, Guangxi and the middle and lower reaches of the Yangtze River. At 18 o'clock tonight, the Central Meteorological Observatory continues to issue an orange warning for heavy rain.
Starting from July 3, the subtropical high began to move northward, which will also push the main rain belt of the mainland to the north as a whole, and the recent rainy situation from Guizhou to the middle and lower reaches of the Yangtze River will come to an end, and it will enter a period of intermittent rainfall from the 4th to the 8th.
At the same time, rainfall will increase in southern North China, Huanghuai and other places. The Central Meteorological Observatory predicts that from July 4 to 8, there will be moderate to heavy rain in the eastern part of Northwest China, North China, Huanghuai, and the southern part of Northeast China, with localized heavy rain. The meteorological drought in some of the above areas will be eased somewhat, but we should also be vigilant that heavy rainfall in the later period may lead to a sharp turn of drought and flood.

It should be noted that today and tomorrow, many places in the north and south of the mainland will have to guard against strong convective weather. Today, under the dominance of the cold vortex, North China, Huanghuai and other places need to be vigilant against scattered thunderstorms, strong winds or hail, and local winds can reach 8 to 10.
Starting tomorrow, as the eastern section of the subtropical high rises northward, the energy conditions and wind shear conditions are favorable, and there will be scattered strong convective weather in North China and Huanghuai. The western part of the subtropical high is still maintained, and the eastern part of southwest China, Guangxi and other places need to be vigilant against short-term heavy rainfall. In this regard, the Central Meteorological Observatory will continue to issue a yellow warning for severe convective weather at 18 o'clock tonight.
2 The high temperature of the "Great Shift".
Simplified version
Middle and lower reaches of the Yangtze River: high temperature, ignition!
North China, Huanghuai: High temperature, extinguished!
Northern Heilongjiang: I'm also hot?!
Detailed version
The change of the position of the subtropical high will not only affect the change of the main continental rain belt, but also the range of high temperature weather.
It is expected that starting from July 3, the subtropical high will strengthen the westward extension and northward lifting, and the heavy rainfall in the middle and lower reaches of the Yangtze River will be downline, and the hot and sultry weather will be replaced, and continue to play steadily, with a maximum temperature of 35~38 °C. For example, Hangzhou, Shanghai, and Nanchang will usher in continuous high temperature weather this week, and Shanghai and Nanchang will be the first high temperature of the year. In addition, Fuzhou's hot weather this week is directly full, and this "endurance" ability is simply terrible.
△ Fuzhou weather forecast for the coming week.
In North China and the Huanghuai region, in the next two or three days, under the influence of the cold vortex and the northward lifting of the rain belt, there will be more rainy weather, and the overall high temperature will also show a reduction trend, with the maximum temperature mostly around 30 °C, and some areas will drop to around 25 °C, temporarily falling back to a state lower than the same period of the year. In cities, such as Shijiazhuang, the maximum temperature for the next three days will be less than 30°C, which is in stark contrast to last week's "hot and piping".
In addition, the heat in the northeast region this week was also unexpected, especially in the northern part of Heilongjiang. As the continental ridge of high pressure that has recently brought scorching heat to Xinjiang gradually moves eastward, starting from the 4th, the maximum daytime temperature from eastern Inner Mongolia to most of the northeast will enter the 30°C+ ranks. In particular, the northern part of Heilongjiang and the northeastern part of Inner Mongolia, which are close to the core area of the warm ridge, have a sudden increase in local high temperature due to the high latitude and long sunshine time.
For example, Mohe is expected to usher in continuous high temperatures from tomorrow to this Saturday. For Mohe, there have only been 32 days of high temperature since 1957, and the next five days of continuous high temperature will break the longest number of consecutive high temperature days in the local area. At the same time, the highest temperature in Mohe on the 4th may reach 40°C, which will break the local record for the highest temperature in July.

The weather in the flood season is complex and changeable, and the high temperature and heavy rainfall are just a different place, so everyone must still be vigilant and not take it lightly! Pay close attention to warnings and forecasts! (According to the WeChat account of China Weather Network)
